CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit under 35 U.S.C. 119(e) of U.S.Provisional Application No. 62/331,339, filed May 3, 2016, and entitledSYSTEMS FOR ATMOSPHERIC WATER GENERATION, which is incorporated hereinby reference in its entirety.

FIELD

The present disclosure relates to systems and methods for atmosphericwater generation, which systems and methods for dehumidifyingatmospheric moisture include filtering and sterilizing the condensedatmospheric moisture. More particularly, the systems and methods forcondensing atmospheric moisture include an indoor subsystem that isseparate from and connected to an outdoor subsystem.

BACKGROUND

Atmospheric water generation systems typically comprise a coolingelement, such as a coil, that is cooled below the dew point to condensewater from the atmosphere. Condensed water is collected in a tank,passed through one or more filtration systems, and dispensed as drinkingwater.

However, many such systems typically expose collected water to variousatmospheric pathogens during the collection and filtration processes.Further, these systems are known to harbor and grow bacterial pathogens.As a result, although water may be collected from the atmosphere andfiltered, there may still be some uncertainty as to the safety of thewater for drinking.

In addition, many existing systems comprise an integral collection andfiltration unit, and the unit, which may be disposed outdoors, may nottherefore include a tap or water dispenser at an indoor location. Or,where integral water generation systems are disposed indoors, they maygenerate unwanted compressor/pump noise. These systems may not, inaddition, include remote access capabilities, requiring users to bephysically present at the system location to operate the system.

It would be beneficial to provide an atmospheric moisture generator thatdid not require users to be present at the atmospheric moisturegenerator, which is commonly an outdoor location, in order to drinkwater from the tap or control the operating functions of the atmosphericmoisture generator. Additionally, it would be beneficial to provide anatmospheric water generator that did not expose collected water toatmospheric pathogens during the collection and filtration processes.

DESCRIPTION

Persons of ordinary skill in the art will realize that the followingdescription is illustrative and not in any way limiting. Otherembodiments of the claimed subject matter will readily suggestthemselves to such skilled persons having the benefit of thisdisclosure. It shall be appreciated by those of ordinary skill in theart that the systems and methods described herein may vary as toconfiguration and as to details. The following detailed description ofthe illustrative embodiments includes reference to the accompanyingdrawings, which form a part of this application. The drawings show, byway of illustration, specific embodiments in which the claimed subjectmatter may be practiced. It is to be understood that other embodimentsmay be utilized and structural changes may be made without departingfrom the scope of the claims. It is further understood that the stepsdescribed with respect to the disclosed processes may be performed inany order and are not limited to the order presented herein.

As stated above, existing atmospheric water generators are frequentlystandalone units that operate more effectively when located outdoors.However, this requires users to be present at the atmospheric watergenerator, and outdoors to retrieve water from the atmospheric watergenerator. Alternatively, existing standalone atmospheric watergenerators may be located indoors to facilitate more convenient accessto the collected water. However, an indoor location reduces theefficiency of atmospheric water generators because indoor air commonlyhas a lower dew point temperature and a lower humidity.

Additionally, atmospheric water generators commonly employ a pump tooperate the cooling element, which pump creates noise that is notdesirable for an indoor atmospheric water generator. Therefore, there isa need for an atmospheric water generator that does not pollute anindoor location, such as a home, with the noise of the cooling elementthat condenses water and takes advantage of the benefit of condensingwarmer, wetter outdoor air, yet still allows a user the convenience ofdispensing water at an indoor location.

The systems and methods disclosed herein overcome the deficiencies ofexisting atmospheric water generators by employing two subsystems thatare separate from one another. This separation provides the benefit ofallowing the collection portion of the system to be located at a remotelocation, such as outdoors, while dispensing water from the secondportion of the system at a tap in a desired location, such as indoors.In this manner, the noise of the collection system does not disturb theuser at the remote location, and the collection system is exposed towarmer and more humid outdoor air that can be more efficiently condensedby an atmospheric water generator.

Existing atmospheric water generators struggle with pathogen exposureand growth in the system. The outdoor air frequently used by atmosphericwater generators contains a variety of pathogens. Existing atmosphericwater generators attempt to eliminate these pathogens with a combinationof one or more filters, LED generated ultraviolet radiation, andexposure to ozone. However, these systems fail to completely removepathogens from the collected water. This is especially problematic atthe interior surfaces and components of atmospheric water generators,which are constantly exposed to moist climates, standing water, and/ormoderate temperatures due to their location within the atmospheric watergenerator. Filters fail to prevent at least some pathogens from passingthrough, LEDs may not provide sufficiently intense ultraviolet radiationto neutralize pathogens only in certain areas of an atmospheric watergenerator, and ozone generators include potential fire hazards, toxicityissues, and higher operational costs, as well as requiring additionalpre-treatment and post-treatment filtration.

The systems and methods disclosed herein overcome the deficiencies ofexisting atmospheric water generators by including a titanium dioxidecoating on various internal surfaces and components of an atmosphericwater generator. In some conditions, titanium dioxide coatingsneutralize pathogens on contact. Such an additional neutralizationelement may further sterilize collected water continually, withoutrequiring the collected water to be pumped through a filter, exposed toultraviolet radiation, or treated with ozone. In operation, collectedwater often sits idle within an atmospheric water generator for longperiods of time between initial sterilization upon collection andstorage, and later dispensation by a user. The relatively long periodsof inactivity allow pathogens to proliferate on internal surfaces of anatmospheric water generator or within collected water. Thus, the passivesterilization offered from titanium dioxide coatings is beneficialbecause it is constantly neutralizing pathogens, even when theatmospheric water generator is not dispensing or collecting water.

Existing atmospheric water generators are frequently stand alone unitsthat operate more effectively when located outdoors. However, thisrequires users to be present at the atmospheric water generator, andoften outdoors, to control the operation of the atmospheric watergenerator. Additionally, optimal water collection times may be at night,early morning, or on days having particularly beneficial watercondensing conditions, such as a high dew point temperature. Therefore,it may be inconvenient and undesirable for a user to operate anatmospheric water generator efficiently that requires the user to cometo the location of the atmospheric water generator to control the watercollection processes of the atmospheric water generator.

The systems and methods disclosed herein provide remote access andcontrol capabilities using a downloaded smartphone application, which isalso referred to as na “app.”. Thus, users may monitor and change theoperating mode of one or more remotely located atmospheric watergenerators without the inconvenience of having to be present at the oneor more atmospheric water generators.

With reference to FIG. 1, there is shown an illustrative system 100 foratmospheric water generation. The term “atmospheric water generation”can be used interchangeably with “atmospheric water generator,” and theterms are used interchangeably herein. As described herein, the system100 may collect and purify atmospheric moisture to produce drinkingwater.

The illustrative system 100 includes a first subsystem 102 and a secondsubsystem 104. The first subsystem 102 may be coupled, such as by way ofa pipe, tubing, water tube, conduit or other such water transmissionmaterials 106 to the second subsystem 104. The first subsystem 102 maycollect and transfer atmospheric moisture to the second subsystem 104for dispensation as drinking water through a water outlet or tap 108.The water tube 106 coupling the first subsystem 102 to the secondsubsystem 104 allows the first subsystem 102 to be separate from thesecond subsystem 104 and remotely located. By way of example and not oflimitation, the first subsystem 102 may be located outdoors and thesecond subsystem 104 may be located indoors. As a further non-limitingexample, the first subsystem 102 may be in a basement or closet and thesecond subsystem 104 may be in a kitchen.

In operation, water vapor in the air, i.e. humidity, enters theillustrative first subsystem 102 and the water vapor is condensed andcollected from the humid air. The collected water is then held in thefirst subsystem 102 and transferred through the water tube 106 to thesecond subsystem 104, which is indoors. The collected water is thenstored in the second subsystem 104 for later dispensation at the wateroutlet or tap 108.

With reference to FIGS. 2-6, there are shown various views of anillustrative first outdoor subsystem 102. The illustrative first outdoorsubsystem 102 may comprise a first housing 202, a cooling element 204,an air intake filter 206, a plurality of light emitting diodes (LEDs)208, a water collector 210, and a water storage tank 212. Although theillustrative system includes a vent that receives humid air, thecollected water system operates in a pressurized closed loop system thatmaintains an positive pressure between the first subsystem 102 and thesecond subsystem 104. The closed loop system includes a pump (not shown)that maintains the positive pressure throughout the system and serves toovercome line losses due to friction and passive drops over valves,fitting and equipment.

Humid air enters the first subsystem 102 through the air intake filter206, where an initial portion of pathogens is removed from the humidair. The humid air then contacts the cooling element 204, whichcondenses water vapor from the air on to the cooling element 204 as thecooling element 204 suddenly lowers the temperature of the air. Thecondensed water then runs into the water collector 210 due to gravityand is fed into a water storage tank 212. In the illustrativeembodiment, the first subsystem 102 is outdoors where the air is morehumid than indoors. In humid environments, indoor cooling from airconditioning systems reduces the amount of humidity in the air. Thus, itis harder to collect water vapor inside a cool room or structure thanoutside in a more humid environment.

In various embodiments, the first housing may comprise an intake vent224. The intake vent 224 may include a plurality of vent holes or ventapertures that allow air to flow through the intake vent 224 and intothe air intake filter 206.

The housing 202 may house the cooling element 204, the air intake filter206, the plurality of LEDs 208, the water collector 210, and the waterstorage tank 212. The housing 202 may be sealed during operation suchthat humid air is only able to enter the housing 202 through the airintake filter 206. Thus, during operation, the air flow through the airintake filter 206 may be maximized, because humid air is not permittedto enter the sealed housing 202 through unsealed crevices in the housing202. In various embodiments, the housing 202 may be sealed andpressurized.

The cooling element 204 may comprise any cooling element suitable tocondense water vapor out of the atmosphere. For example, the coolingelement 204 may comprise a typical refrigerated cooling element or coilcapable of cooling air passing over its surface to condense water vapor.The typical refrigerated cooling element is operated by circulatingFreon or other such common refrigerant working fluids within a closedsystem at various temperatures and pressures. In particular, a pump orcompressor pressurizes the refrigerant in one stage, and allows therefrigerant to expand in a second stage where the refrigerant absorbsenergy from matter, such as humid air. In various embodiments, theworking fluid circulating in the cooling element 204 may be water from anatural or existing energy sink, such as a well, lake, or river, toprovide an energy efficient cooling element 204. The cooling element 204may be carbon coated to neutralize airborne or surface pathogens, suchas bacteria and other microbial organisms. Similarly, in variousembodiments, the cooling element 204 may be coated with titaniumdioxide, such as by a titanium dioxide paint, to neutralize airborne orsurface pathogens. For example, carbon or titanium dioxide may be baked,painted, sprayed, sputtered, infused, or otherwise deposited on thecooling element 204 to form a coating. In various embodiments, it may beadvantageous to bake the titanium dioxide layer onto the cooling element204 and other system components as described herein, because sprayed orpainted titanium dioxide may decompose, chip, flake, or otherwisedegrade in the presence of liquid water.

In one embodiment, the air intake filter 206 may fit into a removableintake vent panel 207 or a portion of an intake vent panel of thehousing 202. The intake vent panel 207 may include a plurality of ventholes or vent apertures that allow air to flow through the intake vent207 and into the air intake filter 206. In another embodiment, theintake vent panel 207 is removable and has no vent holes or apertures.The interior portion of the air intake filter 206 may abut or face thecooling element 204. The intake filter 206 may comprise any suitable airfilter and may be configured, treated, or adapted to neutralize airborneor surface pathogens.

For example, and with particular reference to FIG. 5, there is shown aninterior (to the housing) portion of the air intake filter 206. Theinterior portion of the filter 206 may include the plurality of LEDs208, which may be mounted to the air intake filter 206 by one or morefasteners, one or more clamps, by an adhesive, by a heat bondingtechnique, by bolts or screws, by an integral manufacturing or formationtechnique, and the like.

In various embodiments, the air intake filter 206 may include carbon ortitanium dioxide to neutralize airborne or surface pathogens. Forexample, carbon or titanium dioxide may be baked, painted, sprayed,sputtered, infused, or otherwise deposited on either or both of theexterior and interior portions of the intake filter 206. In this manner,the air filter 206 may be coated with carbon or titanium dioxide.

With particular reference now to FIG. 6, each of the LEDs 208 mayinclude an ultraviolet LED capable of eliminating airborne and surfacepathogens entering the system 100. In various embodiments, the system100 may include a plurality of strips of LEDs mounted to the air intakefilter 206, and the LEDs on each strip, or the strips themselves, may bevariously oriented in space. For example, the air intake filter 206 maycomprise three strips of LEDs, and each of the three strips of LEDs mayilluminate an axis (x, y, or z) of the air intake filter 206. In anillustrative embodiment, each of the three strips may contain six LEDseach and may extend vertically, along a y-axis, of the air intake filter206. In various embodiments, more or fewer than one LED strip perdimensional axis may be employed to eliminate airborne and surfacepathogens.

The water collector 210 may be disposed under the cooling element 204and may collect and funnel water into the water storage tank 212 as itcondenses on the cooling element 204 and drips under the influence ofgravity into the collector 210. The water collector 210 may be coupledby a funnel, tray, pipe, hose, or equivalent to the water storage tank212. Again, with reference to FIG. 6, there is shown a cutaway of theair intake filter 206, with the cooling element 204. The collector 210may, like the air intake filter 206, be coated with carbon or titaniumdioxide to neutralize pathogens in the collecting water. Water mayfurther be irradiated by one or more LEDs disposed over the surface ofthe collector 210 to destroy and stifle the growth of pathogens.

With reference now to FIGS. 7 and 8, illustrative cross-sectional viewsof the second subsystem 104 are shown. Accordingly, the second subsystem104 may comprise a second housing 214, a pathogen neutralizing module216, a water storage container 218, a water inlet 220, and a wateroutlet or tap 108. The second housing 214 may house the pathogenneutralizing module 216, the water storage container 218, the waterinlet 220, and the water outlet or tap 108.

The water storage container 218 may comprise a tank or vessel, and asshown with reference to FIG. 8, the water storage container 218 maycontain a compressor 222, such as a mechanical spring (e.g., a helicalor coil spring) or a pneumatic actuator, a platform 224, and a waterstorage bladder 226. The platform may be any suitable flat surface, suchas steel sheet metal, aluminum sheet metal, wood, or composite. Thewater storage bladder 226 may comprise an antimicrobial coating ormaterial. In various embodiments, the water storage bladder 226 may reston the platform 224, which may, in turn, rest on the mechanical spring222. As described below, the mechanical spring 222 may expand andcontract as water is pumped into the water storage bladder 226(contraction) or released from the water storage bladder 226(expansion). In other words, the mechanical spring 222 may be compressedto store energy as water is pumped into the bladder 226 and, as water isreleased from the bladder 226 into the tap 108, the spring 222 mayexpand, releasing its stored energy, to squeeze the bladder 226 suchthat water is forced into the tap 108. The mechanical spring 222 may befurther tempered along its length, such that the spring 222 is capableof exerting a constant pressure against the inflating and deflatingwater storage bladder 226 as the spring 222 is compressed anddecompressed. The spring 222 may therefore maintain the water storagebladder 226 at a constant pressure as the water storage bladder 226 isfilled and emptied of water, for example at 12 PSI. However, in otherembodiments, the spring 222 maintains the water storage bladder 226 at asubstantially constant pressure ranging from 10 psi to 14 psi

In various embodiments, the compressor 222 is a pneumatic actuatorcontaining a fixed mass of working fluid (i.e., air, hydraulic fluid).The pneumatic actuator exerts force constantly on the water storagebladder 226. Similar to the mechanical spring 222, the pneumaticactuator may be compressed to store energy as water is pumped into thebladder 226 and, as water is released from the bladder 226 into the tap108, the actuator may expand, releasing its stored energy, to squeezethe bladder 226 such that water is forced into the tap 108. In anotherembodiment, the pneumatic actuator includes a pneumatic compressor andrelease valve that operate in conjunction to modulate the internalpressure of the pneumatic actuator as needed to maintain a consistentforce on the water storage bladder 226.

In various embodiments, the pathogen neutralizing module 216 maycomprise one or more filters, an ozone treatment module, a secondplurality of LEDs, or any combination thereof.

In addition, water may pass through one or more elements comprising thepathogen neutralizing module 216 prior to entering the water storagebladder 226 and/or as the water is released from the water storagebladder 226, as described herein, on its way to the tap 108. Further, invarious embodiments, water may be treated by elements of the pathogenneutralizing module 216 at both stages; that is, water may be treatedprior to storage in the water storage bladder 226 and as the water exitsthe water storage bladder 226. By way of example and not of limitation,the pathogen neutralizing module 216 may include a filter that filtersvarious particles from the water prior to entering the water storagebladder 226. In another illustrative embodiment, the pathogenneutralizing module 216 includes an ozone generator that releases ozoneinto the water storage bladder 226. In yet another illustrativeembodiment, the pathogen neutralizing module 216 includes a secondplurality of LEDs (not shown) that treat water as it exits the waterstorage bladder 226.

The one or more of filters may include at least one of a first sedimentfilter, a second sediment filter, a carbon filter, a first pathogenfilter, and a second pathogen filter. The sediment filters may filtersediment and mineral content from water collected by the system 100. Thecarbon filter may filter mineral, particulate, and other content fromthe water. The first and second pathogens filters filter variouspathogens such as bacteria and other microbial organisms from the water.Water passes through the filter or filters. The filters may besequentially connected to one another. For example, water may flowthrough the first and second sediment filters, then through the carbonfilter, and finally through the first pathogen filter and the secondpathogen filter. A final sediment, carbon, and/or pathogen filtrationstage may be added to ensure water quality.

Any one or more of the plurality of filters may be tubular or flat.Additionally, any one or more of the plurality of filters may be amembrane filter. The membrane filters may have a pore size of 0.1microns to 10 microns. Such filters prevent bacteria, fungal spores, andother pathogenic microorganisms from passing through, therebyneutralizing such pathogens in the filter water. Bacteria typicallyrange in size from 0.5 microns to 5 microns in length, fungal sporesfrom 2 microns to 200 microns, and amoebas from 200 microns to 500microns.

The ozone generator may employ any one or more of the common in situozone generation techniques, such as corona discharge or UVphotochemical generation.

In operation, an air compressor or fan (not shown) may operate withinthe first subsystem 102 to draw air, through vents (not shown) in theintake vent 207 and into the air intake filter 206. As air passesthrough the filter, a carbon or titanium dioxide coating on the interiorportion of the air intake filter 206 neutralizes airborne and surfacepathogens. In some embodiments, many bacteria and other microorganismsare destroyed by contact with titanium dioxide, and pathogens such asthese are neutralized as they make contact with, and pass through, theair intake filter 206. Thus, the system 100 may, during an initialpurification or sterilization stage, neutralize pathogens while watervapor in the air is in a gas phase (i.e., prior to water condensation).

However, in other embodiments, contact with titanium dioxide mayincrease pathogen content. In these embodiments, the various otherelements of the pathogen neutralizing module neutralize the pathogensthat are not destroyed by contact with titanium dioxide. In still otherembodiments, pathogens are neutralized on contact with titanium dioxidein the presence of ultraviolet radiation.

The plurality of LEDs 208 may irradiate humid air having water vapor asit passes through the air intake filter 206 to further neutralizepathogens circulating through the filter. The LEDs 208 may operate inthe ultraviolet spectrum, such as, in an illustrative embodiment, at 254nanometers. In various embodiments, the LEDs 208 may emit other spectraof UV radiation, e.g. 405 nanometers.

As humid air exits the intake filter 206, it may come into contact withthe cooling element 204. The cooling element 204 may be coated, like theair intake filter 206, with titanium dioxide or carbon and/orilluminated by one or more ultraviolet LEDs to further reduce orneutralize pathogens in the intake air. The cooling element 204 mayoperate at a temperature that is below the dew point such that watervapor in the intake air condenses on the cooling element 204 and dripsas it accumulates on the cooling element 204 into the water collector210. Thus, the system 100 may further neutralize pathogens during asecondary treatment, in which purification or sterilization stage—i.e.,when the water vapor has condensed on the cooling element 204 into aliquid water phase.

Referring to FIG. 6, the system includes a controller having a processorand a memory having tangible, non-transitory, computer-readableinstructions stored thereon that, when executed by the processor, causethe processor to adjust the operating temperature of the cooling element204 to a temperature that is below the measured dew point. The dew pointmay be measured by one or more sensors configured to measure the dewpoint in the system 100. The dew point may also be calculated byaccessing online weather databases that include local weatherconditions. In various embodiments, the processor may adjust thetemperature of the cooling element 204 to a temperature that is between1 to 25 degrees Fahrenheit below the measured dew point, so that thesystem 100 does not expend electrical energy beyond what is needed toreduce the cooling element 204 temperature to a temperature that isbelow the dew point.

The system 100 may therefore improve its operating efficiency by varyingthe cooling element 204 temperature to correspond to variations in thedew point temperature. The system 100 may adjust the cooling element 204temperature based upon the dew point temperature automatically or basedupon a manual input by an operator, which may be provided to the system100 by way of an application interface provided on a wirelesscommunications device that is communicatively coupled to the system 100.

Moreover, the illustrative controller 120 may receive further systemstatus information such as a temperature of the cooling element 204, anindoor temperature, an outdoor temperature, an indoor humidity, anoutdoor humidity, and the like from various sensors. The controller mayuse this additional information to further improve its operatingefficiency when varying the cooling element 204 temperature.

In some embodiments, the system 100 may improve its operating efficiencyby causing the controller 120 to engage the cooling element 204 when theindoor and outdoor temperatures vary beyond a certain amount, such as 5°F., 10° F., 15° F., 20° F., or 25° F. In other embodiments, the system100 may improve its operating efficiency by causing the controller 120to engage when the indoor humidity and outdoor humidity vary beyond acertain percent, such as 5%, 10%, 15%, 20%, or 25%. In still otherembodiments, the system 100 may improve its operating efficiency bycausing the controller 120 to engage when certain combinations ofoutdoor temperature and humidity are favorable to water vaporcondensation are measured. For example, outdoor temperatures above 75°F., 80° F., 85° F., 90° F., 95° F., or 100° F. degrees Fahrenheit andoutdoor humidity of 30%, 35%, 40%, 50%, 60%, 70% or higher forcondensing water vapor.

The cooling system 100 may further power on and power off based upon awater level and/or pressure in the water storage tank 212 or waterstorage bladder 226. For example, the system 100 may power “on” togenerate water in response to a determination that the water level ineither of the water storage tank 212 or water storage bladder 226 isbelow 100% of the total water storage capacity. Also, the system 100 maypower off in response to a determination that the water level in eitherof the water storage tank 212 or water storage bladder 226 is less than100% of the total water storage capacity. In another embodiment, thesystem 100 may power off in response to a determination that the waterlevel in either of the water storage tank 212 or water storage bladder226 is 100% of the total water storage capacity of either. In anotherembodiment, the system 100 may power off in response to the waterpressure in either of the water storage tank 212 or water storagebladder 226 is 12 psi, 13 psi, 14 psi, or 15 psi.

The water collector 210, like the air intake filter 206 and coolingelement 204, may be coated with carbon or titanium dioxide and/orilluminated by ultraviolet light are associated with the first outdoorsubsystem. The water collector 210 may funnel water into the waterstorage tank 212, and a pump coupled to the water storage tank 212 maypressurize water in the tank 212 to a specified pressure. In a preferredembodiment, water in the water storage tank 212 is pressurized to apressure in the range of 12-14 psi. In various embodiments, a pressureexceeding 12-14 psi may encourage the formation of pathogens, such asbacteria, in the plurality of filters as water is transferred from thefirst subsystem 102 to the second subsystem 104.

In one illustrative embodiment, a pressure exceeding 12 psi may causeone or more porous elements within at least one of the filters 216 maypermit pathogens to enter the closed loop system second indoorsubsystem. Thus, the system may limit the water pressure prior to andduring filtration to pressures of approximately 12 psi, while afterfiltration (e.g., as water is pumped into and stored in the waterstorage bladder 226), water pressures may also remain approximately 12psi or water pressures may exceed 12 psi depending on engineeringrequirements.

More specifically, water is transferred from the first subsystem 102 tothe second subsystem 104 by way of the illustrative water tubing 106. Invarious embodiments, the tubing 106 may comprise any suitable length,such as any length that is less than or equal to fifty feet. The tubing106 may further, in certain embodiments, comprise any suitablethickness, such as one quarter of an inch, and the tubing 106 may, likethe rest of the system, comprise an antimicrobial material or a materialcoated with an antimicrobial agent.

As water enters the second subsystem 104, it may be stored in the waterstorage bladder 226. As water accumulates in the bladder 226, thebladder may, by its increasing mass, force the compressor 222, uponwhich it rests, to compress. Water may be maintained within the secondsubsystem 104 (e.g., within the bladder 226) in a vacuum (or nearvacuum), such that the water does not come into contact, afterfiltration and/or sterilization at the first subsystem 102 withsecondary or unintentionally introduced airborne pathogens. In otherembodiments, water may be maintained within the water bladder 226 in avacuum. In further embodiments, water may be maintained within thesecond subsystem in a positive pressure. In still further embodiments,water may be maintained within the water bladder 226 in a near vacuum.The second subsystem 104 is therefore, in this regard, a closed orisolated system. The water storage bladder 226 is, in addition, may bemaintained in vacuum or under positive pressure such that the bladder226 is devoid of air.

The illustrative second indoor subsystem 104 may respond to a request oran input, such as a mechanical input provided by an operator of thesystem 100 at the tap 108, to dispense water by releasing energy storedin the compressed compressor 222, such that the compressor 222decompresses or expands, causing water to flow from the bladder 226 tothe tap 108. Thus, the water stored within the water bladder 226 isforced out of the water bladder 226 and through the tap 108 in responseto expansion of the compressor 222. In various embodiments, thecompressor includes a mechanical spring, and the decompression occursalong the helical axis of the spring to squeeze the bladder 226. Thecompressor 222 may be allowed to decompress, when a valve (not shown) onthe tap is opened. In various embodiments, as water exits the bladder226 on its way to the tap 108 the water passes through a series ofsediment, carbon, and pathogen filters. These filters remove orneutralize sediment, minerals, various odors and discolorations, and anyremaining pathogens from the water at this stage.

As described above, the first subsystem 102 may be located outdoors andmay be coupled, by way of one or more water carrying tubes 106, to thesecond subsystem 104, which may be located indoors for convenience andsuch that water can be dispensed indoors. Placement of the firstsubsystem 102 outdoors confers several advantages. For example, asdescribed above, the first subsystem 102 may include an air compressor,which may during operation produce undesirable motor or air compressornoise if placed indoors. The first subsystem 102 may be separated ordecoupled, by way of the water tubing 106, from the second subsystem104, permitting placement of the quieter second subsystem 104 indoors.Generally, the humidity of outdoor air has more water vapor and is,typically, capable of producing a greater water yield than indoor air,which is often pre-filtered and dehumidified by heating and coolingsystems.
